Pr4 O7 -Pr2 CuO4-δ (PCO) thin films were grown on Pt (Pt/Ti/SiO2 /Si) substrates by pulsed laser deposition and their resistive switching behavior was investigated. The resistance ratio RH/L (Rhigh /Rlow ) could be larger than 104, which can be maintained up to 50 cycles and 104 s without detectable degradation. The results show that the Pt/Pr4 O7 -PCO/Pt device possesses excellent endurance and retention properties. The physical mechanism of resistive switching in Pr4 O7 -PCO film could be ascribed to the forming and rupturing of conductive filaments via migration of oxygen vacancies.
